蠕虫状结构

在选定的条件下，通过改变表面活性剂的浓度，分别制备出有序三维立方、二维六方和蠕虫状结构的介孔氧化硅薄膜。

By change the concentration of surfactant in a chosen conditions , Well-ordered 3D-cubic , 2D-hexagonal , and worm-like mesoporous silica films have been synthesized .

扫描电镜（SEM）和透射电镜（TEM）结果表明，我们成功制备了单分散碳微球，而且这些微球内部分布有大量微孔和蠕虫状孔道结构。

Scanning electron microscopy ( SEM ) and transmission electron microscopy ( TEM ) results showed that we successfully prepared monodisperse carbon microspheres and a large number of micropores and worm-like channels were homogeneously dispersed in the carbon matrix of carbon spheres .

结果表明这些单分散的碳半球具有中空的单层壳结构，在这些碳半球的单层壳中分布有大量的微孔和蠕虫状孔道结构。

These monodisperse carbon hemispheres had hollow single-layer shells . Large numbers of micropores and worm-like channels were homogeneously dispersed in the single-layer shells .

然而，纯炭膜的蠕虫状孔结构使其孔道蜿蜒曲折、路径长，气体在孔道中渗透扩散时间长、阻力增大，这就是为什么纯炭膜气体渗透通量低的原因。

However , the gas permeation routes in the carbon membrane is long and winding due to the " worms " - like pore structure , which is the reason of the low gas permeability in the pure carbon membrane .

结果表明，Fe3+离子进入了分子筛骨架，Fe-MSU-1分子筛具有均一的蠕虫状介孔结构，平均孔径约为2.9nm。

The results showed that Fe3 + ions were successfully incorporated into the framework of MSU-1 , and the Fe-MSU-1 material had a uniform worm-like mesoporous structure with about 2.9 nm pore diameter .

当钒负载量小于6%时，载体HMS的蠕虫状介孔孔道结构得到了很好的保持，因此得到的催化剂具有高比表面。

The well-defined Hexagonal mesoporous with uniform pore diameter of The HMS support is retained when the vanadium loading is under 4 % , getting catalysts with high surface area .
